Agreed... clearer, and somewhat more familiar (in standard posix regex sense). Thanks for clarifying @Craig.

However, I am also trying to comprehend the comment by @Choonster:

If someone can share 2 small illustrative examples of when to use which one, or why -- it'd be excellent. I know that I am perhaps asking for too much.

Yep, it's a separate module included with LPeg[1]. It's mostly PEG
notation[2] with a few Lua specific extras. I'm not sure if it was the
best example to use but I find it much clearer to read.
